TAKE-UP FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 254,788, dated March14, 1862. Application filed June 23,1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county ofCnyahoga and State of Ohio, have invented certain new and usefulImprovements in Take-Ups for Sewing- Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilledin the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to a take-up device for sewing-machines; and itconsists in so constructing a take-up and needle-bar that both areoperated by one and the same wrist or pin of a crank or crank-wheel; Italso consists in a thread-retaining device, aswill be hereinafter setforth and claimed.

In the drawings, Figure l is adetached view of a face-plateofasewing-machine having my improved take-up attached, and looking at thesaid face-plate from the rear. Fig.2 isafront view of the crank-wheelwhich operates the needle-bar and my take-up. Fig. 3 is a side elevationof the crank-wheel, showingthe manner of operating the needle-bar andtake-up. Fig. 4 is a view in section of a part of my take-up, showingthe manner of threading the same.

A is a face-plate of a sewing-machine.

B is a heart-cam, which is attached to the needle-bar C and operated bymeans of ai'riction-wheel, a, on the wrist or pin 1) of the crank-wheelD. (See Figs. 2 and 3.)

E is a take-up, one end of the same being pivotally attached to the sideof the face-plate A, or to an arm extending therefrom, as shown in Fig.1, and the other end being provided witha-nysuitablethread-retainingdevice. The thread-retaining device shown, being the oneI prefer to use, is formed by slotting one end 'of the take-up E bothlongitudinally and transversely, as shown more clearly in Fig. 4

of the drawings, and providing the longitudinal slot 0 with a spring,(1. The manner of threading this device is also shown in Fig. 4:. Thespring (I is depressed, as shown by dotted lines, until it has passedthe transverse slot 6.

til it reaches the enlargement at its lower end, when it has alsoreached the hook or turned end of the spring (I. The spring dis thenreleased, and carries with it the thread, as shown.

The take-up E is operated by the wrist b on the crank-wheel D, and isprovided with an irregular slot, as shown, in which the said \Vl'lst 1)works. The thread, after passing through the loop or eye at the upperside of the faceplate, as shown in Fig. l, is threaded, as hereinbeforeshown and described, through the free end of the takeup, and from thencepasses to the needle-bar and needle, and it will be seen that at eachupward stroke of the needle-bar the take-up is also raised, and pullswith it the thread, and at each downward stroke of the needle-bar thetake-up is lowered, as shown by dotted lines in Fig.1, and the thread isloosened between it and the needle.

What I claim is-- 1. Thecombination", with a tak -up lever the free endof which is provided with intersecting longitudinal and transverseslots, ofa spring having its free end located within the longitudinalslot in thearm, the lower end of the spring having a thread-retaininghook formed thereon, substantially as set forth.

2. The combination, with the needle-bar, a cam attached thereto, arotary shaft, and (ran kpin for imparting a reciprocating movement tosaid needle-bar, of a take-up lever pivoted at one side of theneedle-bar, and located between the crank-pin disk and needle-bar cam,andonstructed with an arc-shaped .-lot,within which engages thecrank-pin, which latter imparts motion in both directions to the takeuplever, substantially as set t'orth.

In testimony whereof I have signed my name to this specification in thetwo subscribing witnesses.

' GEORGE W. BAKER.
